tends to fill non-(002) planes, resulting in compact and uniform growth. Meanwhile, the presence of In suppresses corrosion and parasitic reactions, further enhancing the structural stability of the anode. As a result, the Zn-In anode achieves an average Coulombic efficiency (CE) of 99.91% over 10000 cycles. Moreover, the alloy anode can also cycle stably for more than 3200 h in symmetric cells. Full cells deliver high capacity and stable cycling in both coin and pouch configurations. This work demonstrates a synergistic strategy for constructing durable, high-utilization Zn metal anodes toward practical aqueous batteries.
